Dynaflon Fluoroelastomers O-ring (FFKM/FKM/Aflas)
Fluoroelastomers has high temperature resistance, excellent chemical resistance, and mechanical properties are close to general rubber. Common applications: O-rings, oil seals, auto parts and other environments that general rubber cannot adapt to. Depending on the fluorine content and formulation, a variety of functional products are derived, such as FFKM, FKM, Aflas etc.
FFKM, also known as perfluoroelastomers, is the product with the highest fluorine content. Its chemical resistance is similar to that of PTFE, and its mechanical properties are close to that of fluoroelastomers. It is a high-priced and high-performance rubber. The main feature is that it is almost unaffected by all fluids. Generally, the continuous use temperature can last from 260 °C to 290 °C, and the instantaneous temperature can reach 315 °C.
Aflas fluoroelastomer is a brand by Asahi Glass Company, which is used in harsh chemical environments, such as oil drilling works.
